Before rotating the box body, press the telescopic block downward, the first spring is squeezed, the telescopic block moves downward, and the positioning block is pulled downward by the connecting rope, the third spring is squeezed, and then the sleeve that is about to be rotated to the rear is rotated so that the discharge shell is located at the top to prevent fertilizer from falling due to bumps, and loosen the telescopic block. Due to the action of the first spring and the third spring, the positioning block moves upward and connects with the positioning groove to limit the sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention allows the box to rotate by fixing a rotating shaft rotatably connected to the placement groove at the lower end of the box. Before planting the bird's nest fruit trees, the box is rotated so that one of the fixed cylinders is located in front of the vehicle body, and the wheels at both ends of the vehicle body are placed on both sides of the ridge. The ridges can be fertilized by the operation of a spiral feeder. After the bird's nest fruit trees have been planted for a period of time, the two fixed cylinders are rotated to both sides of the vehicle body by rotating the box, and the wheels of the vehicle body are placed between the two ridges. The ridges on both sides of the vehicle body can be fertilized by the operation of a spiral feeder, thereby increasing the utilization rate of the entire fertilization equipment.

[0014] 2.

Before planting the bird's nest fruit trees, when fertilizer is needed, the box body (7) is rotated to rotate one of the fixed cylinders (8) to the front of the vehicle body (2), the box body (7) drives the rotating shaft (24) to rotate, the rotating shaft (24) drives the first bevel gear (33) to rotate, the first bevel gear (33) drives the second bevel gear (34) to rotate, the second bevel gear (34) drives the winding shaft (25) to rotate, the winding shaft (25) loosens the pull rope (22) located in the front, and one side of the pull rope (22) is The screw feeder (13) is still connected to the first double-axis motor (17), and the pull rope (22) located at the rear is tightened. The tightened pull rope (22) pulls the second half ring (23) downward, and the pull rope (22) pulls the first half ring (28) upward through the fixed rope (38). Due to the action of the second spring (31), the insertion rod (36) is pulled downward and disengaged from the slot (35), and the screw feeder (13) on one side of the pull rope (22) is separated from the first double-axis motor (17); d. placing the wheels on both sides of the vehicle body (2) on both sides of the ground ridge, starting the first double-axis motor (17), pushing the box body (7) to move through the pushing frame (1), and the first double-axis motor (17) drives the screw feeder (13) in the front to work, and the organic fertilizer in the box body (7) is transmitted to the ground ridge on the side of the root of the bird's nest fruit tree through the fixed cylinder (8), the sleeve (3) and the discharge housing (6); e. Rotate the box body (7) to rotate one of the fixed cylinders (8) to the front of the vehicle body (2). It does not matter which fixed cylinder (8) is rotated to the front of the vehicle body (2). The rotation can be adjusted by the staff. f. Before rotating the housing (7), the telescopic block (14) is pressed to move downward, the first spring (16) is squeezed, the telescopic block (14) moves downward and pulls the positioning block (5) downward through the connecting rope (15), the third spring (19) is squeezed, and then the sleeve (3) that is about to be rotated to the rear is rotated so that the discharge housing (6) is located at the top to prevent fertilizer from falling due to bumps, and the telescopic block (14) is loosened. Due to the action of the first spring (16) and the third spring (19), the positioning block (5) moves upward and connects with the positioning groove (9), thereby limiting the sleeve (3).
